Over one lakh people have applied for a one-way trip to Mars, as a part of the ambitious $6 bn dollar project that aims to colonise the Red planet starting in 2022. Here are 10 things you should know before you decide to travel to Mars.
A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive.
A spirometer can be used to determine how well the lungs receive, hold, and utilise air. They are also used to monitor and determine the severity of a lung disease and to determine whether the lung disease is restrictive (decreased airflow) or obstructive (disruption of airflow).
